You have 2 red cards (Heart and Diamond) and 2 black cards (Club and Spade).

The first card can be anything.
After you choose it, there are three cards remaining, and two of them are the different color.
So, the probability of the second card being a different color would be 2 / 3, or 67% (rounded).
